Specification of Letters Patent.

Patented April 30, 1907.

Application filed March 4, 1907. Serial No. 360,476.

To all whom it may concern.-

Be it known that I, THOMAS C. J oI-INsoN, a citizen of the UnitedStates, residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in TelescopeAttachments for Guns; and I do hereby declare the following, when takenin connec tion with the accompanying drawings and the letters ofreference marked thereon, to be a full, clear, and eXact description ofthe same, and which said drawings constitute part of this specification,and represent, in Figure 1 a view in side elevation of a gun providedwith my improved telescope attachment, the telescope being shown in itsnormal position. Fig. 2 is a similar view showing the telescope in itsforward or safety position which it takes when the gun is fired. Fig. 3a view of the gun in front elevation with the barrel and magazine insection.

My invention relates to an improved telescope attachment for firearms,the object be ing to provide simple and reliable means for preventingthe telescope from rebounding rearwardly after recoil and striking theuser of the gun in the face.

With these ends in view my invention consists in the combination with agun, of a telescope, swinging mountings therefor, and means forpreventing the telescope from swinging rearwardly after recoil on therebound.

My invention further consists in certain details of construction andcombinations of parts as will be hereinafter described and pointed outin the claims.

In carrying out my invention as herein shown, I employ a spring latchformed at its forward end with a cross-head 2 fixed to the top of theforward end of the telescope 8. The said latch has a yielding shank lmerging at its forward end into the said crosshead 2 and terminating atits rear end in a finger-piece 5 having its lower face formed with a cam6 and a shoulder 7 respectively co-acting in the Order named with thefront and rear edges of the central portion or apeX of the upper end ofthe yoke-shaped front telescope-mounting 8 which embraces the gun barrel9 to which it is pivoted by means of two pivots 10. To support thetelescope in this mounting it is provided with a fixed lug 11 receivinga screw 12 passing trans versely through the mounting 8. Tlhe f reartelescope-mounting 13 of the telescope corresponds to the mounting 8already mentioned, but instead of being pivotally attached to the barrel9 it is pivotally attached by pivots 14 to the receiver 15. Thetelescope is supported in the mounting 13 by means of a lug 16 receivinga screw 17 passing through the said mounting. 1,;

In the normal position of the telescope as shown in Fig. 1, themountings are inclined rearwardly so as to bring the telescope, relatively close to the gun, the mountings and telescope being held in thosepositionsflgby gravity. When the gun is fired the i gun moves rearwardunder the action of recoil, whereby the telescope is virtually swungforward and upward into the position shown by Fig. 2. During thisforward and upward movement of the telescope, the rounded. forward edgeof the front mounting 8 engages with the cam 6 of the finger-piece 5 ofthe latch, whereby the latch is lifted against the tension of its springshank 4 thus in a measure reducing the shock of the forward movement ofthe telescope for which the latch acts as a buffer. When, however, thetelescope reaches the limit of its forward movement, the shoulder 7 ofthe finger-piece 5 engages with the rear edge of the mounting 8 and.prevents the telescope from rebounding on recoil, whereby the telescopeis prevented from flying back, as it were, and striking the user of thegun in the face.

It is apparent that in carrying out my invention, different pivotalmountings from those herein shown might be employed, and also that someother means than the latch shown and described might be used forpreventing the telescope from rebounding on recoil. I would thereforehave it understood that I do not limit myself to the exact constructionshown and described, but hold myself at liberty to make such departurestherefrom as fairly fall within the spirit and scope of my invention.

I claim 1. The combination with a gun, of a telescope, swingingmountings therefor, and mechanical means for preventing the telescopefrom rebounding rearwardly owing to recoil.

2. The combination with a gun, of a telescope, swinging mountingstherefor, and a yielding latch in position to engage with one of thesaid mountings when the telescope is ing and striking the user of thegun in the IQ longitudinally swung forward with respect face. to thegun.
